采用浸渍法制备了以TiO₂为载体的Ni-Co基催化剂，研究了Ni-Co/TiO₂催化剂在水相中催化糠醛生成环戊酮和环戊醇的反应。探讨了Ni-Co负载量、反应时间、反应温度、反应压力、pH对产物的影响。通过XRD、BET、H₂-TPR、SEM等表征方法对催化剂的构成及反应机理进行了研究。实验结果表明，分别以10% Ni-10% Co/TiO₂和20% Co/TiO₂为催化剂，在反应温度为150℃、反应时间为4 h、氢气压力为4 MPa的条件下，环戊酮和环戊醇的生成率达到最高值，分别为52.3%和41%。

TiO₂ supported Ni-Co based catalyst (Ni-Co/TiO₂) is prepared by a typical wetness impregnation method and is used in the conversion of furfural in aqueous phase into cyclopentanone and cyclopentanol.The influences of temperature,pressure,reaction time,pH and different supported contents of Co and Ni in the catalyst on the products are explored.The composition of the catalysts and reaction mechanism are characterized by means of the methods including XRD,BET,H₂-TPR and SEM.The yields of cyclopentanone and cyclopentanol can reach the highest,52.3% and 41%,respectively when the conversion reaction is performed over 10% Ni-10% Co/TiO₂ and 20% Co/TiO₂,respectively at the optimized conditions (150℃,4 MPa for H₂,4 h).
